偏心摆动油气混输泵的动力特性研究

摘要

介绍了偏心摆动油气混输泵的工作原理及结构特点，建立了其运动部件的动力学模型，并对已建立的动力学模型进行了数值计算，最后用实验对理论模型进行验证.结果表明：作用在摆轴上的压差作用力所形成的阻力矩是影响混输泵轴功率的主要因素；进出口压差为1．2~3MPa 时，计算功率与实验功率的相对偏差为1％~38．2％.%Working principles and structural characteristics of a new eccentric swing multiple pump were described.Motion and dynamics mathematical model of the motion parts of the multiphase pump was established.Numerical calculation was performed for a prototype of motion and dynamics mathe-matical model.Finally,experiments verified this theory was feasible.The results show that drag torque which is formed by the differential pressure forces on the swing-axle is the main influence on the shaft power pump.In the import and export pressure ranges of 1.2~3MPa,the deviation of the power input tested and calculated is in the ranges of 1%~38.2%.
